FUEL-PIPE LOCK DEVICE.

Specification of Letters Patent.

' Application filed January 17., 1919. Serial No. 271,745.

To aZZ whom it may concern.-

Be it known that I, FRANK VOGELZANG, a citizen of the United States, and resident of Rock Valley, in the county of Sioux and State of Iowa, have invented a certain new and useful Fuel-Pipe Lock Device, of which the following is a specification.

The object of my invention is to provide a fuel pipe lock device of simple, durable and inexpensive construction.

A further object is to provide such a device which may comprise a series of telescoping valves arranged in a single valve casing, which casing is interposed in a fuel line, the valve being provided with telescoping stems, the stems being provided at their outer ends with means whereby they can be rotated for setting the valves in any desired position.

The entire device is intended to be so constructed and arranged that when the valves have once been moved to inoperative position, it will be difiicult for one not acquainted with their condition to set them in condition forpermitting fuel to pass through.

VVith these and other objects in View, my

irrvention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawings, in which:

Figure 1 shows a vertical, sectional View through the floor of a motor vehicle equipped with a fuel line lock device embodying my invention.

Fig. 2 shows an enlarged, vertical central, sectional view through the valves.

Fig. 3 shows a top or plan view of the dials.

Fig. 4 shows a perspective view of the valve casing.

Fig. 5 shows a perspective view of one of the valve stems.

Fig. 6 shows a perspective view of the under surface of one of the dials.

Fig. 7 shows a top or plan view of the cover cap for the dials, and

Fig. 8 shows a vertical, central, sectional view through said cover cap.

In the accompanying drawings I have used the reference numeral 10 to indicate generally the floor of a motor vehicle having Received in and snugly fitting the-'inte rior of the valve member let is a valve 17 Patented Jul 13,1920.

having the form of a hollow cylinder. The

valve 17 is provided with opposite openings 18, which register with each other and in one position of the valve register with the openings 15 and 16.

- Received within the valve 17 and secured at its lower end to the valve member 14 is a cylindrical sleeve 19, having i'n'its walls opposite openings 20 which register with the openings 15 and 16. It will be understood that the valve 17 is rotatable.

Received within the-sleeve 19 is a rotatable valve 21, having in its walls opposite openings 22 designed in one position of the valve 21 to register with the openings 15 and 16. i

- Received within the valve 21 and Secured at its lower end to the valve member 14*, is a sleeve 23. The sleeve 23 is provided with openings 24. which register with the openings 15. Received within the sleeve 23 is a solid cylindrical valve 26, having an opening27 which in one position of the valve 26 registers with the openings 15 and 16. The valve 26 has an upwardly extending stem 28.

The valve 21 has at its upper end a flange 29 extending inwardly and covering the uppe end of the sleeve 23. At the inner edge of the flange 29 is' an upwardly extending hollow stem 30, which terminates below the upper end of the stem 28.

The valve 17 has at its upper edge a similar inwardly extending flange 31, which rests partially upon the flange 2S) and forms a cover for the sleeve 19. At the inner edge of the flange 31 is an upwardly extending stem having the form of a hollow sleeve 32, terminating below the upper end of the {stem 30.

The valve stems hereinbefore described are 20 l .1 with coacting locking devices 43 and 44.

erably angular in .horizontal cross-section,

as illustrated at 34in Fig. 5.

Mounted on the upper ends of the valve stems 32, 30 and 28 are dials 35, 36 and 37 having hubs'38 provided with angular openand the valves.

ings 39 to receive the angular ends 34 of the valve stems. The hubs 38' are locked to the valve stems by means of set screws 40.

,It will be seen that by loosening the set screws the dial plates 35 may be set in dif ferent positions with relation to the stems and 37 is provided with a series of indicating characters 41.

uita'bly hinged to the plate 33 is a cover 42. The plate 33 and cover 42 are provided Secured to the cover plate 33, near the hinge point of the cover 42, is an indicating finger which extends upwardly and thence laterally above the dials 35, 36 and 37 for furnishing a means by which the various dials ma be set. 1

I n installing my improved device on a car, the valves may be placed in position and the plate 33 assembled, and thereafter the dials may be placed in position on the various valve stems while the valves are in open position. The then positions of the dials with relation to the indicator finger 45 may be ascertained, and the owner ofthe car will then know the combination; that is to say, will know the position in which the dials must be in order to set the valves at open position.

When the driver stops the car and desires to lock the fuel supply, he raises-the cover 42 and turns any one of the dials. Any person who might desire to'tamper with the car would not know which dial to turn first in order to move the valves to proper position Each of the dials 35, 36'

for permitting the passage of fuel through them.

It will be obvious'that my device is of simple arid inexpensive construction, and that it can be mounted as an attachment upon almost any type of motor car, .and that it will serve efficiently to prevent strangers from starting the car.

Some changes may be made in the construction and arrangement. of the various parts of my improved device without do: parting from the essential features and purposes of my invention, and it is my intention to cover by'my claim any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

i I claim as my invention:

In a device of the class described, a fuel line pipe, a valve casing included in said fuel line pipe having opposite registering openings communicating with said pipe, a

plurality of spaced sleeves fixed together at their lower ends, said sleeves having a plurality of registering openings adapted to register with said firstdescribed openings, a plurality of valves adapted to be received between said sleeves and capable of rotation around said sleeves, said valves having openings adapted when in one position to form a passageway between the two pieces of fuel pipe and when in another position to close the passageway, flanges fixed to the upper ends of said valves, said flanges being adapted to overlap each other, telescoping stems fixed to said flanges, whereby rotation of the stems will rotate said valves, said casing having an inwardly extending flange designed tocover saidfirst described flanges, thereby preventing the removal of said valves without first removing said casing, said valvecasing being held in position by said fuel line pipe.
